Show full forest utilization and new byproducts by products to conserve timber plastics and new uses will greatly reduce amount of timber cut annuala annually y while wood and wood pr products have found thousands of new uses many of which will be important in postwar era the final effect will be a definite conservation of standing timber many of the new plastics plywood and other items are being manufactured from bark sawdust and other sawmill wastes and then are being utilized to replace high grade lumber products the development t of hardening of wood will conserve the lumber to a greater extent it will give at least a 50 per cent increased life to lumber products makin making their replacements considerably slower fireproofing of wood products will also conserve the rapid diminishing stand of timber the intensified competition between wood products metals plastics ceramics glass and other products will directly aid in forest con the drain on our forests timber cut plus loss from fire insects and diseases has been exceeding the growth by 50 per cent naturally this is ia a condition condit iori that cannot continue unabated fire control reforestation es and insect control will be a must in the postwar period less wood will be utilized for heating purposes more wood waste will go into plywood and other products to replace timber these will prove the th e answer to timber conservation to a large extent new increased utilization of wood and wood waste can provide an industry of million dollars and offer employment for additional men it is as entirely possible that the new industry will replace the lumber industry as such making the products byproducts by the backbone of the forests among the war improvements with lumber is the reduction of swelling and shrinking characteristics of normal wood this process alone will result in a tremendous saving in wood products the plywood is not only fireproof but is moisture resistant plywood dates daes back hundreds of years but it was only when weather resistant glues were developed that this material assumed major importance as a material to replace lumber for outdoor uses especially housing and farm structures lin and ur alloy commercial tk 6 whole forests of pine oak birch beech cedar and maple are going into the gigantic crucible of war via the shipyards and other war plants most of these logs formerly would have been waste today due to chemurgic uses even the bark is playing an important part p iv SP 7 PT 42 Z ze ng R affo vow speed is the watchword of the wood product byproduct by industry within a few days these logs will have arrived at the mills and be transformed into ships chemicals plywood and other products byproducts by wood products owe their origin to chemical or physical modification of the basic cellulose lignin units of minute wood structure these products base their invention on the knowledge that lignin dignin can be cited by chemical treatment and made to flow it is now possible to mold thase these products into any shape or design desired in the past 70 per cent of the average wood taken to the mills was waste un under der present development most if not all of this waste is eliminated this saving alone will even the spread between the growth and the drain upon the standing timber war has developed some unusual uses for wood products in every country in europe factories are turning out textiles from wood smokeless powder shell casings molasses shoes imitation leathers and glycerine are also developed from wood wastes europe has also proven that sugar and food can be extracted from wood most of these unusual uses euseb will not be carried into the postwar period forests are a renewable resource I 1 with proper management and protection they can be made to produce continuing crops but it if an abundant and permanent timber supply is assured positive action will have to be taken on an individual and a nationwide nation wide scale now that the real value of timber has been realized it will become commercially profitable to practice rigid reforestation by individuals and government |
